Similar to http://forum.xda-developers.com/showthread.php?t=2375050 (except I made an efs backup), my SIM card is no longer recognized. Backed up everything using default Clockwork Mod recovery settings 6.0.3 on Wind T889v.
I installed roms in this order:

Of course, I noticed the SIM card was no longer being recognized upon installing Slim
In the past GT-N700 ROMs for T0LTE have worked fine. I was running BeanStalk 4.4.2 W0etweaks with working phone and sim card. The issue occured when installing.
As if my phone had not detected a SIM card, phone number, IMIE SV, and IMIE show up as "uknown".
I am not too sure how to proceed? Ideas?
I've had similar issues with some versions of TWRP where flashing an Omni 4.4 nightly would leave me with no signal and an unknown IMEI. Flashing the very same ROM with CWM would work. (Odd, I know.)
FWIW I just flashed the latest t0lte Omni nightly with TWRP t0lte 2.7.0.0 earlier today and everything's been fine.
Another thing to look into is SELinux and making sure it is set to permissive.

Tried with CWM 6.0.3 with no luck. Tried with Phiz Touch 6.07.9-t0lte, and no luck as well. I will try TWRP t0ltecan 2.7.0 shortly. Which version of CWM did you get it to work with?
Tried setting SELinux to permissive via https://play.google.com/store/apps/details?id=com.mrbimc.selinux, but it made no difference. Am I supposed to do something after I set it to permissive?

I was not able to install TWRP t0ltecan 2.7.0, but I was able to install TWRP t0lte 2.6.0. And the installation, along with any other 4.4 ROM fails with the following error:
Code:
set_metadata_recursive: some changes failed
E: Error executing updater binary in zip '/external...
Error flashing zip 'external_sdcard/omni-4.4.2..
I will try other ROMs with CWM 6.0.3 and Philz TouchWiz. Hopefully, I will figure something out...
Could this be the same problem?
Hmm... I've been troubleshooting different ROMs with no luck. But could this be the solution? http://forum.xda-developers.com/showthread.php?t=1970338

Indeed, I had to flash my modem. For users like me, of the T889V, download the modem from http://androtransfer.com/?developer=cmenard&folder=SGH-T889 and flash the file using the recovery of your choice (I used TeamWin 2.7.0). Note that you will need to install openrecovery-twrp-2.7.0.0-t0lte.zip (and not the can version openrecovery-twrp-2.7.0.0-t0ltecan.zip, as that version will not install). You can flash your modem at any time, and it will not affect your current ROM. You don't need to clear dalvik cache, cache, or do a factory reset; just flash the modem file.
This problem occurs because you try to install a ROM that's not for your phone. So in my case, OmniRom included a modem not for my version (international). Because the modem is normally not included in ROM packages, it doesn't matter which ROM you install. To get back to a working state, you need to flash your original modem.
Hopefully this helps someone.
Uhh... not really

Well, turns out I was wrong. I'm back at where I started. Somehow, after rebooting once with the new ROM, I started getting the exact same problem with no service and unknown IME.
Tried flashing the modem with no luck.
Is there a reason why this would only work for the first time? Is it possible that I installed an app that caused this problem?
Will update if I find any solutions...

Tried flashing stock via Kies. Still the same problem.
Also, ran into this video: https://www.youtube.com/watch?v=Pai4BH3AWq8 but on Stock, there was no option 6 or way to see FTM.
On custom 4.4 roms, you get the "Mobile Network not Available" when trying to fix null IMEI (update: IMEI shows up as null/null).
Any help would be appreciated.

The Modem Likely Burned
After a long week of research, I believe I determined the cause of the issue: when I flashed the Slim Rom, it burned out my modem on my motherboard, as the ROM was not built for my Note variant (T889v). I spoke to a repair technician in my local area, and he was quite certain that my modem had been damaged (likely burned) from the unsupported ROM installation. He was very familiar with such a scenario. It means you have to replace your phone if you want to be able to use your SIM card, make calls, use data, etc..
The modem consists of small transistors (radio, and other communication parts). Even if you take apart your phone, you won't be able to see burn marks. The only way to be *somewhat* sure this is the case is to try recovering your EFS partition to an earlier point when your phone was working. Luckily for me, I had this. I also had a modem backup. Both failed. If all of this, and flashing stock fail, you've got a hardware issue.
This means you're out of luck if you want to send your phone in for repair; Samsung will know from that (corrupt) data in the modem that you broke your phone from flashing a custom ROM. So it doesn't matter if you triangle away or flash stock -- you're out of luck if you have a warranty. You will be charged the retail value of your phone + shipping, so you're probably better off selling your phone for parts.
It's a sad day for me, but a dawn for new days where I will make SURE that my phone's model is supported.
Let this be a cautionary tale for you as well.

why would they know? flashing the stock upgrade flashes a modem as well. could just as easy be a bad upgrade. if you don't tell them they wont know
also what slimrom did you download that did this? sorry I just reread the OP. Neither of the roms you mentioned would do that to your phone. I have flashed many roms from both of those devices and never had an issue.

I doubt it was a bad upgrade, as I've tried everything possible to fix my phone. Recovering EFS partition, flashing stock with Kies, recovering modem, flashing the original ROM that worked earlier... nothing fixed it.
The problem occurred immediately after installing Slim. Then, any rom I installed after that did not solve my problem.
Pretty sure it's a hardware problem.
Greetings,
I really don't want this to be a repeat post, so I have spent many days now searching for this answer, not just here on XDA if I was honest, I have links to prove it
The aim is to give a little new life to my old phone, and get off the 4.1 build it is on.
With that said, in summary, I have tried a few different custom ROMs; Cyanogenmod 11 - 13, stable to nightly. PAC MAN ROM for Lollipop, some other roms for KitKat I found else where, but in all these I have not been able to get 4G to work. I understand about updating the Modem, and got the latest version from DocHoliday77's post for the Galaxy S3, in point of fact I tried every modem version for 4.3+ on there
But for all this, and it's been time consuming I never managed to actually get 4G to work as stated
I tried playing with settings in Test Mode (*#*#4636#*#*), changed preferred settings, added APN's, rebooting during certain phases of the moon ... but somehow it all avails me diddly.
Finally I have genuinely tried searching for info on if this just isn't going to happen and that's how it is, but somehow I found lots of posts about other models or networks that made it work more than something saying this won't work (putting aside the info on CM 11 that states it's a known issue and won't work on some build I forget).
Which leads me to this post: I wondered if anyone could point me in either the direction of a 4.4+ custom ROM or other ROM, compatible for SGH-T999 (T-Mobile Galaxy S3), that has working 4G. Or how I can get 4G to work on one of the ROMs I have already tried, kind of partial to a nice CM but I am willing to venture.
Also happy to just hear other input about giving new life to the phone so any feedback welcome
Thanks for your time!
NOTES
======
Using TWRP 3.x for flashing
Phone is rooted
IMEI is visible & fine on custom ROM
4G works on stock ROM
not experienced at this but willing to read
Edit: something I had not noticed before, I install Gapps for most of my tests but never use it. I just tried to download from Play Store, it acts as though I have no connection; waiting to download appears, then eventually it says waiting for network. Yet I am able to browse the net fine with the phone floating between 3G & H+. I don't know if that might help, so figured I should add it.
Is the phone running the latest bootloader and modem? Maybe both are needed to properly get 4g on all Roms?

That's a really good question, let me see if I can find out how to get my bootloader info and I'll get back to you.
May I ask what the latest bootlader is for the SGH-T999, or where I could find this so I can compare it? I couldn't seem to find it, though the most resourceful post I did find related was T999 UVDMD5 Firmware / Bootloader by mnasledov, though it is also a little outdated it appears, I haven't read my entire way through it yet sorry, I also know the phone is a little outdated too .
So that wasn't too bad to find out
I don't have the latest bootloader if that should match the baseband I install.
Where after a ROM install I get my baseband to T999UVUEOH1, but the bootloader stays on T999UVDLJA.
I haven't quite found where to get the latest bootloader just yet, though I did really spend the last few minutes discovering about the bootloader; if you or someone could find the time to point me in that direction that would be awesome
Simplest way to make sure you have the latest would be to flash the most recent stock rom from sammobile.com in Odin.
Thank you very much @audit13, I do appreciate the time you took out to help me and I also appreciate the point in the direction of what next.
I'll go dig into that for a while and see what to do to be sure, before I start
Looks like this is the latest one, so I will give this a shot : PDA T999UVUEOH1 & CSC T999TMBEOH1, version 4.3.
So just as a quick question, since I've never upgraded the bootloader in this fashion etc., from what I have read this is a one way street correct? And since I am upgrading to stock, then I guess will I lose root, which I will have to go back down the path of for a reinstall, or could I flash my old back up over this from TWRP and in that fashion have the latest bootloader, but keep everything I have for the moment as I investigate a ROM that will offer 4G.
I guess what I am getting at is even if having the latest bootloader and some other ROM with the latest baseband doesn't give me 4G still, can I go back in terms of the OS version to my 4.1.1 and keep things as is with a newer bootloader?
I will investigate this myself too, I just always preferred some additional input when discovering things where possible.
I do appreciate your time, thanks again!
No, you cannot run stock 4.1.1 on a 4.3 bootloader unless it is a custom 4.1.1 rom based on a stock touch wiz rom.
I do not think it is a problem to run the latest bootloader and modem as the latest custom ROMs often require an updated bootloader and modem.
Once on a 4.3 bootloader, you can't downgrade to something older.
Thanks again @audit13, that matches what I have read, I appreciate the confirmation!
Looks like I will be undergoing a re-root etc. so I'll get my information together, have a little more read, see what I need to back up and then jump down the rabbit hole
I'm grateful for your time and help.
If you decide to run a custom rom, just flash a stock rom, then immediately flash twrp via Odin, then install the rom and gapps. No need to root before hand.
Ahh ok, that would have made the most sense. However I didn't have an opportunity to check back on this thread until now so even though you had awesome speedy reply I missed it.
I did manager to successfully flash the stock ROM from Sam's. It did also update the bootloader so THANK YOU very much for that.
I had to fiddle a little to get Odin to recognize the my Galaxy S3 in the end it was simple: after I installed Kies to get the drivers on, I disabled WI-Fi (I use it for my dev work, and then it didn't try to spend time getting other drivers and it all went great. But that's just a note incase maybe one day someone else reads the thread and wonders how, this might help.
I'm just actually restoring a couple f things on the stock ROM, I figured I would have it ready in the event a custom ROM doesn't suit immediately, as I find one I like, then I have a back up of the stock ROM on 4.3 to revert to. Incidentally I just used TWRP manager from Google play store to install TWRP, hopefully it's the same as the flash, except now I know I rooted when I didn't have to
@audit13 Thanks, I know I keep saying that but I appreciate your time the same way I would hope someone else appreciated mine.
Incidentally once ready I will post an update here about the success of getting 4G on Cyanogenmod 12 or even 13 maybe, or someone of the other custom ROM I try, to share that info.
So just an update, I can confirm even with both an updated bootloader and matching updated baseband there is still no 4G on Lollipop Cyanogenmod 12, haven't quite tried any other yet, that was the one I liked the most but I will carry on and get a list as I have time then update here.
If there are any further suggestions I'm all open to them
Thanks [email protected]
Do you get 4G on a stock ROM? You have an LTE capabale sim? You get 4G on another phone with the same sim card?
Right, this SIM gets 4G on 2 other phones it's been in, on this phone on stock ROM it gets 4G too. Reverting back to stock backup in TWRP, from CM12 looks like it tripped knox I think it is, so now the warranty bit is 1 oops. But I managed to Odin back to 4.3 stock, so now I also need to see if I can try to flash maybe to CM 11, which is 4.4.x, or if maybe I'm stuck here. If I can find out I certainly will update the result of 4G testing.
You've been really patient & helpful thanks!
First let me say I'm a noob. I've rooted and jailbroken devices but I admit it's all from falling instructions. I rooted my s3 a while ago and installed twrp 1.0.8.7 yesterday. I did a full wipe including system and all catches and installed the latest nightly of cm13. Everything is running great. I don't know if this helps but maybe it's your process. Good luck!

That's really helpful thanks @Shack70, since updating to 4.3 I have only tried CM 12, I can certainly give 13 a shot, & you have 4G working then please?
incidentally I have actually recorded every step I performed, in the event I repeat this again or I had to explain it. But my process maybe at fault I agree; I rooted my phone with towelroot. Installed TWERP manager (3.0.2 something, maybe I should try 1.0.8?), rebooted into recovery & first thing was take a full backup on stock. Then I did a factory wipe, & advanced wipe. Then installed the ROM, wiped dalvik/cache. Installed Apps, wipe dalvik/cache, reboot
Hopefully that's not too much? I just wonder if any of those steps raise alarm?
Edit: mind if I throw a few questions on here at you please @Shack70?
what do you wipe from the options please?
after the install, do you run any other wipes please?
how did you get TWRP on your phone? Not sure if that or version matters but I'm willing to try

In twrp I wiped system and all caches before installing the rom and gapps. I installed an older version of twrp using Odin and updated it to 2.0.8.7 using the twrp app in the play store. Yes I have 4g/lte. I've seen it switch from lte to h+ to 3g depending on my location so I'm sure it's working correctly. The camera and Bluetooth also work fine. I hope this helps, I'm still learning and most of what I've done is just by following others instructions here at XDA.

I definitely appreciate the reply thanks!
I gave the latest nightly CM 13 a shot just now, 7/31/16 version essentially. Not finding any issues with the ROM, can't get 4G to show up no matter what though , even with changes and attempts to APN settings etc. None the less maybe to give my phone a rest I'll just stick with this a while and decide if a newer nightly comes out I want to try, or better yet a stable version at some point. Then I can verify how much I really miss my 4G I guess.
All the previous attempts, including this one always results in 3G to H+ network with no issue, it's just that 4G that never shows up for me.
Incidentally without a serious search around I couldn't even find TWRP 2.0.8.7, it's not on the TWRP manager version I have so curious, I ended up just going with 2.8.0.7, thinking maybe it was a typo?
Otherwise I basically run the same type of install you mention, I also clean dalvik, cache, system & data in my case. Just to confirm that.
I have a slightly off topic question here, if I decide to go back to to stock I was wondering, if i went from UVUEOH1 4.3 JB build, to the previous UVUENC2 4.3 JB build; because I've seen this available as a clean route 66 version, is this still considered a downgrade and a bad idea? I'd be flashing with Odin from @DocHoliday77 post here.
@Shack70, thanks for the input, thanks for the guide on your steps, glad I've confirmed I'm doing the same even if I can't get my 4G, hopefully someone on a Galaxy S3 T-Mobile, went through this found a solution, and maybe will let me know what they did too, not sure if you are on T-Mobile or not.
@audit13, also thanks, you've been replying plenty too and I appreciate that also!
One small thing I just came across looking over the logs of the install.
When flashing CM 13 with TWRP, I noticed it said the Target: samsung/d2tmo/d2tmo:4.3/JSS15J/T999UVUEMJC:user/release-keys.
Is it normal and OK for it the be referencing a different baseband/bootloader than what I actually have on my phone?
UVUEMJC vs the UVUEOH1? Where the one as named by TWRP flash is 2 versions older than what I have installed? Not necessarily stating this is an issue, just asking please if this is normal, and I also understand it could be something I have overlooked in my reading, it's been a lot of reading
I would not worry about the referenced baseband as flashing CM13 does not change the bootloader or baseband during the flash process.

Hi guys.
I have tried to take a logcat of my phone when it bootloops upon restarting after install. Here is the code I used:
Code:
adb -d logcat>C:\adb>Bootloop.txt
However, the output file is empty.
My issue is that I can install any stock-based ROM, but not any custom ROMs (CM or AOSP). When I try to install custom ROMs (CM or AOSP) it always bootloops.
So I am trying to trace the phone when it bootloops. My PC does recognise the phone, as I get the message "This device can perform faster if blah, blah, blah".
Is there another way I can trace the boot up process to find out what errors its throwing out?
Thx in advance.
theKramer
I don't know if USB Debugging is turned on my default on custom ROMs - it isn't on stock ROMs, so logcat wouldn't work via ADB until that would be enabled, which if the custom ROM bootloops from the very start, obviously you wouldn't be able to turn it on.
Have you re-wiped Cache, Dalvik/ART and Data? Flash the appropriate Bootstack? Try moving what you want to keep from your internal storage, eject your MicroSD card/keep it ejected and wipe/reformat your internal storage from TWRP. You can always turn the phone off from TWRP after flashing the custom ROM/Bootstack and then eject the card. Last but not least, try flashing the TOT to start fresh, reroot with the Stump app, put TWRP on with TWRP Manager, and flash the custom ROM and Bootstack like that, although if you go back to stock again after that, I recommend flashing the TOT again before doing so, as some people have trouble with signal or mobile data coming from non-stock or international-stock based ROMs.
Edit: Just noticed you're on the D855, so I don't know the TOT situation there - I only know the VS985, but the advice still stands.

Hi @roirraW "edor" ehT
This is a long ongoing issue. Basically it surfaced after flashing back to stock as I was having random reboots and thought it might be custom ROM related, but after flashing stock I still had the reboot issues, so figured out battery was toast so changed that and reboot issues were resolved.
But since flashing stock MM on my D855, I cannot get any custom ROM (CM/AOSP) to boot on my ROM except Bumped 5.0.1 ROMs.
I can install any stock or stock-based ROM without any issue, however, custom, no go. The funny thing is that I was running custom ROMs on my phone for more than a year without issue. I could throw any custom ROM at it, and where other people might have issues, my phone would always run them flawlessly.
Not anymore
I have flashed stock Lollipop about 7 or 8 times (via LGUP and LG Flash Tool 2014) and stock KK about another 4 times, so I should have blown out any MM remnants at this stage.
The weird thing is that my phone doesnt boot up with stock based KK either (all of them just hang on bootup), but LP or MM is no issue. I am running LIMITLESS ROM v10.2 at the moment (based on v30a). I cannot remember if I tried v10b actually, I did so many of them..
I have rooted from LP each time, and it is always successful (I have used 3 or 4 different rooting methods) and TWRP is successfully bumped each time.
I have tried numerous versions of TWRP (2.6/2.8/3.0/3.0.2).
I have done a full wipes (cache/dalvik/data/system), even including a format data after and still no luck..
The reason I was asking about methods to get some kind of log info during bootup was so I could maybe get some info on why it doesnt boot custom ROMs..

Hi! Argh. Sounds really frustrating! Bear with me since it sounds like you know what you're doing and again I have the VS985. Among the 100% stock unrooted you flashed, did you only flash KDZs or is there a TOT available and did you try that? The reason I ask is that TOTs flash more partitions than KDZs and can fix problems that KDZs and ROMs can't. I can personally attest to that but once I experienced it and asked an experienced developer, it became clear that's expected, and when I extracted the partitions out of the VS985 10B TOT and compared to the KDZ I indeed noticed one or two more partitions.
Again, don't mind me if I'm telling what you already know. The other thing is the Bootstack situation, although I haven't ever experienced a bootloop due to the wrong Bootstack, only non-working modem or dangerous combo of our Marshmallow sbl1 partition along with the BUMP-vulnerable 12B aboot (bootloader), necessary for TWRP and for root on Marshmallow. Reference this VS985 post if needed http://forum.xda-developers.com/showpost.php?p=63438031&postcount=2. I don't really expect that to be the issue and since you tried from a variety of stock ROM situations, I wouldn't have expected you to have an issue with every combo you tried.
Edit: actually, the remaining item is the MicroSD card. I know it sounds silly but it's happened. Try it without the card and see what happens. While you're at it, try with the SIM ejected too just for the heck of it, won't hurt to try.
Good luck! Hope you figure it out.

Hi.
I didnt know that about there being more partitions in TOT vs KDZ files actually..
I have tried flashing without SD card also already.. I haven't tried without sim card, so why not
Is there a specific reason you mentioned flashing v10b, by the way?

In the case of the VS985, 10B is the first or earliest build we have, and we have a TOT of it, so I was just using it as an example. I've only ever noticed a leak of one TOT per variant of a device at the most, but if you have more than one available I would choose the earliest.
Mostly useless information to you, but the VS985 does have a 10B KDZ, but it's 10B_01, whereas the TOT is 10B_03. 10B_03 was the official release so it can get OTAs, and 10B_01 was a leak so it can't. From what I've seen, the sub-build _## is only available as part of the filename when you get a hold of the KDZ and TOT. 10B for the VS985 is also the easiest to root because we can just use the Stump app with its brute force option. For us, rooting gets more complicated after 10B and putting TWRP on gets more complicated after 12B. Both 10B and 12B are still KitKat. 23C and 24B 5.0.1 are rootable via PC/USB/adb script. As far as I remember, 35B 5.1.1 and definitely 46A through 48A 6.0 has no method of permanent root, only KingRoot on 35B through 47A which gives temporary and suspicious root.

So, I haven't actually flashed v10b as I have handed my phone in to a phone repair shop as I have been having a number of hardware issues such as wifi not working, high temperatures at the back of the phone and SIM card detection issues (most likely related to the phone heating up).
However, before I had handed it in to the shop, I flashed a custom kernel (Gabriel stock-based) on the stock ROM I was running at the time, and that reminded me that I have flashed Gabriel kernel on a number of different stock and stock-based ROMs, and if I flashed a stock-based custom kernel, I also got the same bootloop error.
So I was wondering if that might help in any way to pinpoint what is going on with my phone...

So my feeling is that there is something up with my boot image, even though my phone is rooted and bumped and TWRP is bumped, there is something my phone doesnt like in AOSP/CM or modified stock-based kernels that is not visible in LG stock.
Is there any tool/script that I can run that would collect info on the boot process...

I'm not very knowledgeable about logs or experienced collecting or looking through them, but maybe collecting a logcat through adb (over USB) while booting would help? You'd have to have USB Debugging turned on, and make sure it stays on across reboots - there's a common issue that is easy to resolve where if USB Debugging doesn't stay on after you reboot, turn it on, plug it into a PC, manually switch the USB connection mode on the phone from MTP and PTP and back to MTP and then disconnect the cable, and it'll stay on then.

So, I was suggested the app Liveboot, which was created by Chainfire of SuperSU fame. This app outputs a log to the screen and to a log file on the device of all the calls that are made during bootup (with user selectable level of detail).
Running this app, I did two traces. One with just stock LG and the second after flashing a modified stock kernel..
The stock log is 21KB, the log from when I flashed the modified kernel is 904KB.
Liveboot Stock
Liveboot with kernel
This is not an issue with the modified kernel per se, but with some settings in modified kernels. Any way to pinpoint the offending code/parameter?
This is not directed at you "roirraW "edor" ehT", but to any and all that could help me to figure out what is going on..

Just wanted to say thanks for a reminder about that app. I had even tested the app when it first came out and I somehow keep forgetting about it.
So I have isolated the issue to some kind of hardware issue.
If I leave my phone turned off for a while with battery out, I can get it to boot custom ROMs. I have tried with 2 different batteries, so its definitely the phone itself. If I reboot the phone once the phone has booted up, then it boot loops again, even if the phone is only booted for a few minutes.
I had to debick my phone a couple of months ago using the short circuit method (due to some stupidity on my part) and it seems that that has fried something in my phone.
Since I brought my phone back to life I have been having issues with Wifi and SD-card slot not working, plus lots of heat and terrible battery life.
I would love to know though what it is in custom ROMs/Kernels that causes my phone to bootloop.
It would be great if I could isolate that somehow.
Anybody have any ideas, by any chance?
Hello.
The short story is I found one s3 t999 in the drawer and it had 4.x.x ROM. Without paying much attention I flashed the latest TWRP and installed Lineage 7.1.2, but I get "No SIM card" error and am essentially without a network. I'm using a non-tmobile SIM card.
The problem synopsis:
The S3 T999 yields "no SIM card" error with anything beyond Android 4.x.x.
- Tried with Lineage 14.1
- Tried with the latest 7.1.2 OCtOS
- Tried with a LP 5.1.1 OCtOS rom
they all say NO SIM CARD and subsequently "No Service".
Once I restore my touchwiz 4.1 ROM via TWRP - I get network reception and I can make and receive calls.
Can anyone walk me through the problem? I work with linux and flash my other phones with ease, which means I can execute any suggestions momentarily.
THANKS
You need to flash the latest stock ROM, then twrp, then custom ROM.

If I understand correctly, I need to Odin-flash the latest stock rom, which I found it to be JB 4.3. Will this affect my SIM lock situation, seeing as I don't use a tmobile SIM.
Also, Odin requires that I enter "download mode", which TWRP (currently installed) does not seem to have. Odin does not 'see' the s3 connected (whilst in recov. mod).
Does that mean I need to flash a stock recovery first, and if yes, where do I get it and does it matter which stock recovery is being installed?
Flashing the latest stock rom should not affect the sim lock.
You can boot to the bootloader from twrp.
Just flash the stock with Odin, no need to flash anything before hand.

Quite right, I was about to sideload-flash a stock recovery I unearthed here, before I noticed in TWRP in the Advanced menu having the "Download" option right next to sideload, so I booted directly into download mode Odin'd the latest stock rom I found (JB 4.3) and I do still have cell reception.
Does that mean I go into DL mode now, sideload TWRP and proceed to install Nougat (and hoping to have network access)
THANKS A BUNCH
You can flash the tar version of twrp from Odin. Then flash custom ROM, and enjoy

ALL DONE.
I Odin'd TWRP 2.8.6, from there I sideloaded TWRP 3.1.1 then upgraded via IMG install from within and installed OctOS 7.1.2 nightly.
Would you recommend Lineage over OctOS?
Thanks for the tips!
You could have install twrp 2.8.6 and flash the 3.1.1 zip from recovery.
Sorry, I can't make any rom because I haven't owned an s3 for a few years.
Glad you got it all sorted

Unfortunately, right off the bat, LED notification isn't working when a call is missed. I tried to call my number to inspect reception and when the call was registered as missed - no notification light is present - at all. Despite being enabled in settings.
Some custom ROMs have bugs so I recommend trying others until you find one you like. I used to flash my s3, s4, Nexus 5, LG g2 all the time and would come across minor bugs. At least your sim works with newer custom ROMs.
I'm now using an iPhone but still get the urge to hop back to android.

Quite right. I nandroid all of my ROMs so I can give few a spin and return to the one I fancy the most.
And yes, my SIM is now recognized and communications flowing . All I needed was the latest stock rom requirement tip and I was done.
Thanks for that.

Fux's sake! I spoke too soon.
Overnight, the phone (with Nougat) lost network again and in the morning showed "no SIM card". A restart remedies the problem for about 10 minutes before it completely refuses to acknowledge its SIM .
I downgraded with Odin to JB 4.3 and it appears to have network coverage for about two hours now. I'm about toss this piece of garbage 'fone' in the bin.
Is there any reasonable explanation as to why this idiot of phone of mine looses connection, just willy-nilly?
Maybe these nougat roms are too buggy. How about some older cm roms?
Freakin' antique isn't holding service more than few hours (at best) regardless of ROM installed. Even if there is a sequence of actions that can make this piece of garbage 'fone' work well - I'm no longer interested in investing a single minute further. Goes in the bin, end of.
Life's too short.
Just to update those who'll likely one day google and find this.
After going back and forth for as many days... my personal reason for losing connectivity on the s3 was because of a FAULTY SIM CARD. Had it replaced and network coverage came flowing.
As for those wishing to upgrade to Nougat or MM as I have, YOU NEED TO UPGRADE TO THE LATEST STOCK ROM, BEFORE MOVING ONTO NOUGAT.
Matter is now closed.
Hi, I'm replacing a lost Moto G3 TE with a Moto G5 (xt1671 dual sim) that should be coming in the mail on Monday. I'd like to do whatever mods I want to my phone right away, before activating my google account on it and everything. So, I'd really like any advice any of you can give as to preferred custom rom with root that I should put on my new phone, so I can get to it right away. I've already found the thread to unlock it (same process as in past mostly), and I've found the guides for putting on TWRP (either 32-bit or 64-bit). So, now I just need to decide which custom ROM to use. Please advise!
I've also had a Moto G2 in the past. I've unlocked and used custom roms and root on all my phones so far, from Cyanogenmod 12.1 to AOSP Extended, ViperOS, and LineageOS. My wife's Moto G2 has Oreo on it (through AEX) and we're enjoying it (I had her add me as an account until I get my new phone). So, I'd like to continue using an Oreo system if possible, and I'd even prefer AEX, but it seems that it's discontinued for the Moto G5. Is that correct?
My overall goals for a custom rom are, in order of priority: reliability, speed/performance, battery life, and customization options. I found that AEX balanced all of that well on our past phones. Is the discontinued AEX for this phone reliable, or not? I've also seen the LineageOS thread and the KAOSP thread and have glanced at a few others. I use google accounts and half their apps for sure (so I'll want to install a GApps package with it). And I see there's a possibility to unlock RAW/DNG files for the camera, which I'd really like to try (as I prefer raw file editing instead of JPGs). And the customizations I like (if still possible) are mainly involving the way the launcher responds - I like having the navigation buttons hide, or to swipe up to get them back, I like being able to modify the status bar, etc.... typical customizations that were usually available in AEX that I've used. I also use root for file explorer and a few other functions - I used to always use SuperSU in the past, but just recently started using Magisk (on the Moto G2) and it seems good, though I'm open to any recommendation about which root to use.
So, please fire away! Please give your suggestion as to which currently available custom ROMs are stable, have good performance, good battery life, and offer standard customization, plus which I can root. I appreciate any suggestions and any advice you can give, especially regarding if there's a recommended rom but if it has known issues and any known workarounds. Also, I'd appreciate advice anytime today or tomorrow (since it'll likely be the afternoon or evening of Monday +3 GMT time - Madagascar - that I'm able to start working on unlocking it, installing custom recovery, etc.). But even if the advice is late, I might still be able to use it. I know this is a bit much to ask, but please give your own opinions freely!
Oh, by the way, do I need updated Motorola drivers, or will the motorola drivers and adb/fastboot I installed last time (for the Moto G3 TE) keep working with the new phone? The unlock thread I've found here doesn't say anything about motorola drivers or adb/fastboot. Thanks in advance!

Thanks for the response! Is there a stock oreo available? And is stock rooted still customizable (like with AEX or something - can I install some sort of thing to let me customize it more?). And is there a debloated version of the stock rom available? I saw one thread on here about a debloated stock rom, but it looked like it was still nougat.
If it's possible to customize the stock rom further, please point me in the right direction. And if not possible to customize it further... then are you suggesting that any of the custom roms available aren't very stable to be used well for a daily driver?
Again, thanks for your response and also for any more feedback you can give!
So, I have my phone now and it came with stock Nougat. I've unlocked it, and I'm currently working on getting TWRP, Dm-verity thing on it, and then magisk. After that can I still update it to Oreo or not? Please advise. Thank you!

Crud, that sucks! I was already finished rooting and everything on magisk, then I let the OTA update download and when it restarted my phone, it just automatically sends it into recovery (TWRP) every time now! I tried to install this TWRP stock Oreo (dirtying flashing it) hoping it would fix the boot-loop-to-TWRP-recovery problem, but it didn't. So now I need to figure out a way to get back to the original, so I can start over and try again.
I'm trying to do a factory reset and try again, but in TRWP it says ""Failed to mount '/data' (Device or resource busy)'" This sucks! Any ideas where I can go or what I can do (such as some fastboot commands or something) to get it all working again?
EDIT: It does reboot to bootloader though, so it's not hardbricked. Just need to figure out what to do from here. Thanks for any help!
try to flash via fastboot only boot, recovery, oem and system from oreo, then aply update, then root
Thanks! I downloaded the firmware (for latest Nougat) from this thread: https://forum.xda-developers.com/g5/development/stock-upgrade-to-official-stock-oreo-8-t3823598
Then I flashed everything they said through fastboot (ignoring the modem stuff) because I'm still downloading the oreo firmware right now anyway (my connection is quite slow). At first the bootloader got stuck and said "error" and I was freaking out thinking I'd hard-bricked it. But I turned it off and on again anyway and it loaded fine back into nougat for that latest version.
So now I'm downloading the latest stock Oreo and I'll probably try to ADB sideload it.
Which root do you recommend? I have the Magisk I did for nougat that worked great - 11.6 But there's this thread here (https://forum.xda-developers.com/g5/how-to/guide-how-to-root-stock-oreo-8-1-soak-t3832347) that talks about what seems like a complicated way of doing Magisk 15.3 and then getting it up to 16. What do you suggest?
magisk 17.1 its ok, but you have to flash only partition that i said, not full firmware, and DONT flash the bootloader and GPT partition
---------- Post added at 06:11 PM ---------- Previous post was at 06:10 PM ----------
better let the phone to update ota for latest security patch, dont flash via fastboot
OK, I installed the stock oreo through ADB sideload (it wouldn't read my storage for some reason).... then I reinstalled TWRP, no problem... then installed Magisk 17.1 (per your suggestion) and then the apk for the manager. Everything's working great! Didn't even need that dm-verity thing.
I'm still looking into the mods I can do to it now that it's rooted (such as changing boot logo and boot animation, adding that 'camera 2' setting, etc.) So I'm not sure I'm at a finished product yet, but I'm definitely at a stable rooted oreo with all my regular stuff installed, so that's a good place to start! I've made a nandroid backup here in case any of my further experimenting messes it up.
Thanks again for your help! And if you can give any suggestions towards the best way to customize the look (for example - is nova launcher still the best way to do that?) or other aspects of the system UI, while still being on this stock rom, then please let me know. I'll look up how to get that better camera mode working.

Could you help me with this: if I backup my system (everything) with TWRP.... can I then switch to a custom rom to try it out (in case I want a different user interface, more tweaks, etc.) and if I don't like it can I easily switch back to the stock rom nandroid backup I have saved in TWRP (thus restoring my previous state, but without having to start from factory reset)? Or would it be difficult to switch back - like would I have to redo it through fastboot or something and factory reset, etc.?
I'm asking because in the past I never used the stock rom much and I definitely never switched between a custom rom and the stock rom. Once I went for custom rom, I didn't go back - so I don't know if it's as simple as restoring a nandroid backup or if it's much more effort. Please let me know. Thanks a lot!
you must be very carefully because most of the custom roms need twrp on 64 bits, now you have official twrp 32. When you come back from custom roms 64bit to previous nandroid backup, you must install 32 bits twrp, otherwise you may lose the imei of the phone, just read very well when you want to do something risky

OK, thanks a lot for that helpful info! So just to clarify to be sure: basically, if I want to switch back and forth, I'll install the 64-bit twrp first, then the custom rom(s). Then if I want to come back to my stock image backup, I re-install the 32-bit twrp (like the one I'm currently using) and then I can just restore my nandroid backup I took of the stock and all is well? And it's not risky if I do it like that?
yes, its correct that
